Hello there,
Many people have complained that the change from {\centering foo\par} to \begin{center}foo\end{center} adds spacing in their documents and is not acceptable. Actually, the reason why this has been changed is because the old syntax was really broken, and in particular reLyX had problems with it. It occured to be today that \begin{centering}foo\end{centering} works perfectly well. Before I make the change I have to ask: would people be pleased with it? JMarc
